A question of party realignment and
interest groups
• How do parties change their issue positions?
– My argument: “A small set of single issue groups and

stand on a issue.”
– Case: Over the past three decades, the Republican
party and Democrat party have become increasingly
divided on the abortion issue.
– Theory & method: “Networks”
